Re: uClinux without Flash (again) - Page 3

Altera_Forum · ‎11-08-2005

I decided to give uClinux a try on my custom board, but I only have an SD card slot, no CFI. When reading the install guide for uClinux, and when trying it, it won't let me build a kernel project without a CFI device present? Is there any way to get around this? It seems odd that I can't build the kernel and run from DRAM, and then write to the SD Card if I wish to boot...

Thx!

I just got the NiosII for linux CD from Altera, but it was not installed properly withou quartus for linux.

I'd like to setup the cross compiler env. in linux PC. But I cannot access the marc's web link:http://scorpius.homelinux.org/~marc/nios2.html (http://scorpius.homelinux.org/~marc/nios2.html) in China. Only the NiosII for linux CD, What should I do ?

You don't need to intsall anything - copy the binary folder from the linux CD to your linux distribution (it's like H-i386-linux etc... or something), put that folder in your path, and then:

make ARCH=nios2nommu CROSS_COMPILE=(prefix of the binary)- hwselect SYSPTF=yourptf.ptf

then menuconfig...

then just regular make.

1. remove root=/dev/mtdblock2 ro

2. enable <*> Initramfs

3. setup Initramfs source file(s)

but after build the kernel , gavin the following errors:

It looks like you have initrd enabled - turn it off, you do'nt need it - just turn on Initramfs and point it to the source tree.

It looks like you are still using Cygwin; this whole thread has been about how you can't use Cygwin for initramfs http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif You may want to try this with linux...

now I develop linux kernel in linux(redhat 9.0)

1. copy /bin/nios2-elf-.... to pc from CD of nios2linux

2. set PATH

3. make hwselect ; make menuconfig ; make (like you stated out)

the .config is much like you post in this thread.

here is linux log

Thank jdhar and hippo so much, I worked out the right vmlinux, which can bootup with initramfs.

---------------------------------------------------------------

I crated ROOTFS half-automatically & half-manually

1. zip win pc ROOTFS

2. copy to linux pc

3. unzip -a in order to dos2linux

4. modify them properly: such as symbolic link files (ln -fvs * *)and /dev (mknod)

5. ln -fvs ./busybox init

---------------------------------------------------------------

I tested by :

1. ftp vmlinuc to win pc

2. nios2-download -g vmlinux

3. test telnet, ping .... ok

---------------------------------------------------------------

other problems:

1. I just got vmlinux in <linux-2.6.x> directory. I'd like to build out vmlinux.bin in order to let u-boot to boot or flash-programmer. How to do it ?

2. Could you send me the webpages about nios2-linux toolchain in marc'shttp://scorpius.homelinux.org/~marc/nios2.html (http://scorpius.homelinux.org/~marc/nios2.html) to jwq815@sina.com?

"all of the thread is talking about how to build the kernel under linux"

Altera_Forum · ‎12-13-2005

> I'd like to build out vmlinux.bin in order to let u-boot to boot or flash-programmer.

> How to do it ?

For u-boot:

1. Optionally compress the linux binary.

2. Create the u-boot image file from the linux binary (or compressed binary).

3. Load the image file into ram.

4. Execute the u-boot "bootm" command.

1.

-----------------------------------------------------

In redhat, when I

make ARCH=....

it just built out vmlinux, which is used for "nios2-download -g vmlinux" to debug in SDRAM. I'd like to get vmlinux.bin, which is used for nios2-flash-program.

is it also nios2-elf-objcopy??

2.

-----------------------------------------------------

there is a exe file in <plugs>/<microtronix>/application/bin/elf2flt.exe

but how to get elf2flt in redhat?

I cannot surf marc's page to build toolchain.

Altera_Forum · ‎12-14-2005

Regarding Q1, I'm not sure, I tried doing the same at one point, but I don't think I ever got it...

Regarding elf2flt, check the linux distribution CD where you got all the linux binaries from. If it's not there, I'm afraid you will have to build the toolchain somehow... or at least get those binaries. You can probably email Marc himself and ask for binaries.

Altera_Forum · ‎12-15-2005

1. There is no elf2flt in the linux distribution CD. The source is in the examples/software/linux/utils/elf2flt. But you need libbfd to build it. It should be better to do the buildroot following the marc's page.

2. "nios2-elf-objcopy -O binary vmlinux vmlinux.bin" will create the raw binary file.

I agree with hippo - the toolchain is ultimately the best way to go... I tried working with the windows one, and it's just so much slower and you can't automate it like with linux - so I would definitely advise trying to build it.
